3Com Switch 8800 Family IPsec Module Configuration and Command reference Guide

286 CHAPTER 17: AAA/RADIUS/HWTACACS CONFIGURATION COMMANDS
Parameter
ip-address: Specifies a source IP address, which must be the address of this device.
It cannot be the address of all zeros, or class D address, or network address, or an
address starting with 127.
Description
Use the radius nas-ip command to specify the source address of the RADIUS
packet sent from NAS.
Use the undo radius nas-ip command to restore the default setting..
By specifying the source address of the RADIUS packet, you can avoid unreachable
packets as returned from the server upon interface failure. The source address is
normally recommended to be a loopback interface address.
By default, the source address is not specified, that is, the address of the interface
sending the packet serves as the source address.
This command specifies only one source address; therefore, the newly configured
source address may overwrite the original one.
Example
# Configure the security gateway to send RADIUS packets from 129.10.10.1.
[SecBlade_FW] radius nas-ip 129.10.10.1

Parameter
authentication-server-down: RADIUS authentication server goes down.
accounting-server-down: RADIUS accounting server goes down.
Description
Use the radius trap command to configure the RADIUS server to send a trap
packet when it goes down.
Use the undo radius trap command to configure the RADIUS server not to send a
trap packet when it goes down.
By default, the RADIUS server does not send a trap packet when it goes down.
